Forked from Let's make a face with D3.js!

This example constructs a smiling face from basic SVG shapes using D3.js v5, selecting the root `svg` element and appending a grouped hierarchy of circles, rectangles, and an arc-based mouth. The code uses D3’s `select`, `append`, and `attr` methods for DOM manipulation, with the mouth path generated via `d3.arc`. A two-stage `transition` with a 2000-millisecond duration animates the eyebrow group’s `transform` attribute, moving it downward and back, simulating expressive movement. The face is centered by translating a group to the SVG’s midpoint, with fixed pixel offsets controlling eye spacing, eyebrow size, and vertical placement.

Let's make a face with D3.js!

This example creates a smiling face from basic SVG shapes, with its eyebrows repeatedly moving up and down. It demonstrates fundamental D3.js DOM manipulation by appending and styling circles, rectangles, and a path for the mouth. The code uses `d3.select`, `d3.arc` for the mouth, and chained `transition().duration()` calls to animate the eyebrow group’s transform attribute. The face is centered via a translated `<g>` element, with eye spacing and offsets defined as numeric constants.

Let's make a face with D3.js!

This example uses D3.js to construct a smiley face from basic SVG shapes, including circles for the eyes, rectangles for the eyebrows, and arc-generated paths for the mouth and nose. The code demonstrates fundamental DOM manipulation by selecting an SVG element and appending grouped elements with explicit coordinate transforms. Animated behavior is implemented through chained `transition` calls, moving the eyebrow group upward and back down over two one-second intervals. The visualization relies on D3’s `select`, `arc`, and transition APIs to show how static shape creation and simple attribute animation work together.

Let's make a face with D3.js!

This example builds a smiling face out of basic SVG shapes, with animated eyebrows that move up and down. Using D3.js v5, the code selects the SVG element, appends and positions circles for the eyes, rectangles for the brows, and an arc-generated path for the mouth. A transition chain on the eyebrows group animates the transform attribute over two two-second intervals, creating a subtle, looping expression change.

Let's make a face with D3.js!

A smiling face is drawn with SVG shapes, with its eyebrows animating up and down in a repeating loop. The example demonstrates fundamental DOM manipulation in D3.js v5, using `select` and `append` to build circles, rectangles, and a path. The mouth is created with the `d3.arc` API, and the eyebrow motion relies on chained `transition().duration()` calls to alternate the transform attribute, creating a simple, continuous facial animation.

Let's make a face with D3.js!

A smiling face drawn with SVG elements animates as its eyebrows repeatedly move up and down. Built with D3.js v5, the example uses selection methods like `append` and `attr` to construct circles, rectangles, and an arc-based path for the mouth. A chained `transition` with a two-second duration shifts the eyebrow group's transform, creating the looping motion.

Let's make a face with D3.js!

This example builds a smiling face from basic SVG shapes using D3.js, with animated eyebrows that move up and down in a looping transition. The code selects an SVG element, centers a group, and appends a circle for the head, circles for eyes, rects for eyebrows, and a path for the mouth generated with the `d3.arc()` helper. Using `d3.transition()` and `.duration(2000)`, the eyebrows shift vertically twice, creating a repetitive motion. The demonstration focuses on fundamental DOM manipulation—such as `.append()`, `.attr()`, and chained transitions—while rendering entirely in SVG with no external data.

Let's make a face with D3.js!

This example demonstrates fundamental D3.js DOM manipulation by building a smiling face out of SVG shapes, with animated eyebrows that move up and down. A yellow circle forms the head, two circles serve as eyes, rectangles become eyebrows, and a path generated with the `d3.arc` helper creates the mouth. Using a `transition().duration(2000)` chain, the eyebrow group toggles its vertical translation, shifting it downward then returning it to the original position. The code explicitly binds SVG elements via `select` and `append`, relying on D3 v5’s modular imports for `select` and `arc`.
